REVOLVINGRACK SHOW CASE.

Application filed .Tune 2D, 192.2. Serial No. 569,616.

ing-Rack ShowV Cases of which the ollowi ing is a specification.

This invention relates to improvements in revolving rack show cases.

The object of the invention is to provide an automatic closing means for the slot in the fioor or base of such showcase for accommodating -the movable supporting column thereof.

Objects pertaining to details and economies of construction and operation will appear from the detailed description to follow.

I accomplish the objects of the invention by the devices and means described in the following specification. The ,invention is clearly delined and pointed out in the claims.

A structure which is a preferred embodiment of my invention is clearly illustrated in the accompanying drawing forming a part of this application, in which:

Fig. I is a horizontal sectional 'view ythrough a show case embodying the features of my invention, taken on a plane above the revolving rack of the show case.

Fig. II is an enlarged detail view ofmy improved automatic cover means for the slot, the column being shown in ksection and I the base or floor being brokenaway at each side, the adjustment' being indicated by` -guideways 14;, a filler of veneer or fiber dotted lines.

Fig. III is4 an enlarged detail sectional view through the slide means and the transverse sliding` supporting column, taken on line 3-3 of Figs. I and II.

Fig. IV is an enlarged detail longitudinal sectional view taken on line /l-A- of'v of Figs. I and II, showing details of the slide.

Fig. V is an enlarged detail sectional view taken on line 5-5 of Figs. II and III and VI, showing the connection of one of the' tails.

it is apertured to accommodate the able column. l

In theb drawing similar numerals of refle'rence refer to similar partsthroughout the several views, and the sectional views are taken looking in the direction of the little arrows at the ends of the section lines.

Considering the numbered parts of the drawing by their numbersrl is the base of 'the show case;` 2 is the rear wall; 3, 3 are the end walls; 1, L1 are the receding doors; 5 is the rack supported on the cross base arm 6, carried on the column 7 disposed in the aperture 8 of the slide in the trans- -verse'slot 9 in the floor 10 on the base 1.

The receding revolving rack and case supported on the column are of a well known construction and are exemplified in my Patent No. 1,023,186, to which I refer for de- IVithinthe slot 9 I dispose the slide made up of adjustable 'sections "1,1 and 12, the section 12' being prqvided with upwardly projecting end stops 13. The `sections 11 and 12-have an interlocking coupling 121 V(see Fig; IV). These slides aresupportedv on guideways 111,14 at each side, the rear end of tlieslide '11j sliding intoV a pocket 15,`having a floor 150 which is connected by key hole slot'A 151 to the guide 14 by the downwardly projecting key orl button 1411 having a head 1412 to engage the said key hole slot 151.

The' ,slide 11 is lperforated at 8, as indicated, and is, at that point provided with a bottom 'plate 110 which rides upon the board 111 being ,placed between the bottom plate A110 and the top part 11 of the slide, to serve as a buffer to prevent noise.

The slide 11 is provided with little integralrunners 112 which travel on the floor 150 of the pocket 15. "Guard rails 17 are securedabove the' guideways by screws 19, 19', a floor 16 'extending between the front ends of said guideways to cover theslot at that point. The cover 2O is disposed over :the pocket 15 and is held inplace by screws 21.

From this description it will be seen that when the rack with its column is swung to the front of the case (see Figs. I and II), it will pull the slide 11 out oit' the pocket 15 and cover the slot back of the column as it is withdrawn. The section 12 of the cover will slide upon the guides 14 above the slot completely covered while the rack is being swung or pulled out. On the reverse movement the rear end of the section 11 of the slide will run into the pocket 15,

the front portion will be withdrawn until it engages by the interlocking joint 121 with the section 12, when it will be withdrawn until the stops 13 engage the co-operating stops 18, which insures the complete opening of the slide and the stopping of the same at a predetermined point.

Theser parts, it is clear, are very readily and securely assembled by the arrangements that I have shown. All rattling is avoided by the means illustrated so that the cover glides smoothly to place. I have described this structure in the form preferred by me, and I wish to claim that form specically because of its: merit, and I also desire to claim the invention broadly, as pointed out in the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1. In a revolving receding rack show case structure, the combination of the floor with its slot and the rack with its supporting column movable in the said slot, of guideways at each side of said slot extending into a covered pocket at the rear and into a depressed portion at the front, detachable key hole slot joint between the said guide- Ways and the floor of said rear pocket, a slide made up of sections with interlocking ends disposed in said ways, the rear one of which is perforated to lembrace the said column, supporting contact shoe means for the rear section of said slide, stop means for the front section of said slide to insure its opening to cover the slot when the case is closed, and retaining strips above the said guideways notched to co-operate with the said stops at the front, asspecified.

2. In a revolving receding rack show case structure the combination of the floor with its slot and the rack with its supporting column movable in the said slot, of guideways at each side of said slot extending into la.

covered pocket at the rear and into a depressed portion at the front, a slide made up of sections with interlocking ends disposed in said ways, the rear one of which is perforated to embrace the said column, supporting contact shoe means for the rear section of said slide, stop means for the front section of said slide to insure its opening to cover the slot when the case is closed, and retaining strips above the said guideways notched to co-operate with the said stops at the front, as specified.

3. In a revolving receding rack show case structure the combination of the floor With its slot and the rack with its supporting column movable in the said slot, of guideways at each side of said slot extending into a covered pocket at the rear and into a depressed portion at the front, a slide made up of sections with interlocking ends disposed in said ways, the rear one of which is perforated to embrace the said column, stop means for the front section of said slide to insure its opening to cover the slot when the case is closed, and retaining strips above the said guideways notched to co-operate 1yvih the said stops at the front, as specie fr 4. In a revolving receding rack show case structure the combination of the floor with its slot and the rack with its supporting column movable in the said slot, of`guideways at each side of said slot extending into a covered pocket at the rear and into a depressed portion at the front, a slide made up of sections with interlocking ends disposed in said ways, the rear one of which is perforated to embrace the said column, and stop means for the front section of said slide to insure its opening to cover the slot when the case is closed, as specified.

5. In a revolving receding rack show case structure the combination of the floor with its slot and the rack with its supporting column movable in the said slot, of a slide made up of telescoping sections disposed to collapse at the front and cover the said slot when the case is open, and to open to cover the front of the slot when the case is closed, co-operating as specified.

6. In a structure of the class described, the kcombination comprising a rack with a supporting column disposedA in a slot, of a telescoping slide adapted to collapse and eX- pand to cover the slot in the. front of said column.

In witness whereof, I have hereunto set my hand and seal.
